Help windows is screwed up !!!

I can not access any of my applications and I do not have a windows xp cd to reinstall windows, I can not even access any of the .exe files, and not even system restore will work, not even when in safe mode I have not seen this problem before can somebody please help me ?

 

See if this will do it>

To start your computer by using the Last Known Good Configuration feature, follow these steps:
1. Start your computer.
2. When you see the "Please select the operating system to start" message, press the F8 key.
3. When the Windows Advanced Options menu appears, use the ARROW keys to select Last Known Good Configuration (your most recent settings that worked), and then press ENTER.
4. If you are running other operating systems on your computer, use the ARROW keys to select Microsoft Windows XP, and then press ENTER.

Not sure if you will need the xp cd though.

 

Sorry already tried that no luck.
